Sigma thermal O/L relays are designed to meet the special protective needs of motor control circuits. Overload relays allow harmless temporary overloads (such as motor starting) Without disrupting the circuit and they will trip and open a circuit if current is high enough to cause motor damage over a period of time. They can be reset once the overload is removed. The thermal overload relays are used With the Sigma AC power contactors to prevent short circuits and current-overload.
A Sigma Current Transformer is a device used to transform primary currents to a standardized secondary current suitable for measurement and protection purposes in electrical systems.

HRC (High Rupturing Capacity) fuses contain a fuse wire in it, which carries the short circuit current safely for a given time period. During this period, the fault can be removed. If not, the fuse will melt and remove the circuit from electrical supply, keeping your appliances and devices safe from damage. Sigma fuse links and fuse bases are produced in compliance With international standard TS EN 60269-1 and the power losses are even lower than the values required.
